Öğe Evaluation of Toll-Like Receptor Expression with Clinicopathologic Variables in Endometrium Cancer(Yerkure Tanitim Yayincilik Hizmetleri As, 2018) Bakbak, Berat Berrin Gencoglu; Ilhan, Tolgay Tuyan; Pekin, Aybike; Kerimoglu, Ozlem Secilmis; Yilmaz, Setenay Arzu; Kebapcilar, Aysegul; Dogan, Nasuh UtkuObjectives: Clinical evidence supports the association of toll-like receptor (TLR) with abnormal cell proliferation and cancer. In this study, we investigated the expression of TLRs 2, 4, 5, and 6 in healthy endometrium and endometrium cancer to study the relationship of these receptors' expression with carcinogenesis. Methods: Patients who had undergone a hysterectomy owing to endometrium cancer (group 1, 66 patients), endometrial hyperplasia (group 2, 14 patients), and other reasons besides endometrium cancer (group 3, 20 patients as controls) were included. The cases in the first group were classified by histological type of the cancer, stage, grade, and size of the tumor. In all the cases, expressions of TLRs 2, 4, 5, and 6 were assessed, and the relationship of these receptors with clinicopathologic signs was analyzed. For immunohistochemical staining, nuclear and cytoplasmic stainings were considered positive. A Chi-squared test was used to assess the correlation of the groups. A p<0.05 was considered significant. Results: The mean ages of patients in groups 1, 2, and 3 were 59.8 (range 33-83), 48.3 (range 40-59), and 53.4 (range 38-84) years, respectively. All types of TLRs were highly expressed in both types of endometrium cancer (groups 1 and 2). TLR expression was observed with a ratio of 87.9% in group 1, 100% in group 2, and 35% in group 3. There was a statistically significant association of TLR 2 among the three groups (p=0.000). TLR 6 expression in both group 1 and group 2 was significantly higher than that in the control group (p=0.000, p=0.000, respectively). In addition, TLR 6 was higher in cases with late-stage cancer (p=0.033). Regarding tumor grade and the size of the tumor, no association was found between TLR 2 and TLR 6. Conclusion: TLR 2 and TLR 6 were significantly more expressed in cases with endometrium cancer and endometrial hyperplasia. In addition, the presence of TLR 6 may indicate the presence of late-stage endometrial cancer.Öğe Evaluation of Toll-Like Receptor Expression with Clinicopathologic Variables in Endometrium Cancer(Yerkure Tanitim Yayincilik Hizmetleri As, 2018) Bakbak, Berat Berrin Gencoglu; Ilhan, Tolgay Tuyan; Pekin, Aybike; Kerimoglu, Ozlem Secilmis; Yilmaz, Setenay Arzu; Kebapcilar, Aysegul; Dogan, Nasuh UtkuObjectives: Clinical evidence supports the association of toll-like receptor (TLR) with abnormal cell proliferation and cancer.

In the FIGO grading scheme, both architectural and nuclear grade are taken into consideration. However, the specific impact of solid growth alone on endometrioid endometrial adenocarcinoma outcome is not well documented. We sought to assess the degree of impact of solid growth on lymphovascular space invasion (LVSI), myometrial invasion, tumor size, FIGO stage, lymph node metastasis (LNM), relapse-free survival (RFS) and disease-specific survival (DSS). Methods Paraffin blocks of 269 patients treated for endometrioid endometrial cancer were retrospectively analyzed with morphometry for solid growth percentages. Results A statistically significant cut-off value of 1% solid growth was found for predicting LNM and advanced stage (III or IV), myometrial invasion and LVSI (p < 0.001) and a cut-off value of 8% was found for predicting adverse survival outcome (p < 0.001). The mean DSS was significantly higher in patients with < 6% solid growth compared to patients with 6-50%, 51-75% and > 75% solid growth (p < 0.001). Although, the mean RFS and DSS were lowest in patients with 51-75% solid growth, this did not reach statistical significance in comparison to 6-50% and > 75% (p > 0.05). Conclusion Although > 75% solid growth was most significantly associated with many of the adverse prognostic factors, this subset did not provide prognostic superiority in predicting adverse survival when compared to subsets within 6-75% solid growth. In conclusion, although no statistically significant difference in survival was found among subdivisions of architectural grades 2 and 3, solid growth, especially >= 8%, appeared to be an independent prognostic factor for survival in patients with early-stage endometrioid endometrial cancer.
